I have a 2004 600rr. Installed a hotbodies undertail exhaust kit and added resistors about 5 rides ago. No problems. Went for a ride tonight and went down my drive way (very steep) and when I got to the road I went to accelerate and the red light came on and the bike lost power for a couple seconds. The light went off and I continued. Went down another hill later and slowed for the stop sign, pulled the clutch and the light went on.....rpms went down....and bike stalled out. Started right back up, took off and got some gas because it was low and I thought it would be that. Was on flat ground through town and it happened again...lost power with the red light on. I continued and it was ok but running a bit sloppy. Any ideas? I changed the oil 100miles ago.
